(3) FIG. 2 illustrates an exemplary embodiment of a separable self-binding strap device in operation, in accordance with the present disclosure.

DESCRIPTION OF THE EMBODIMENTS

(4) Embodiments of the present invention will be described with reference to the accompanying drawings, wherein like parts are designated by like reference numerals throughout, and wherein the leftmost digit of each reference number refers to the drawing number of the figure in which the referenced part first appears.

(5) As summarized above, embodiments of the present invention provide a novel Velcro-covered bi-stable band device for quickly creating a securely bound loop or strap from which a heavy article (such as a paint-can or an electric saw) can be hung from a hook or rod or similar attachment point, or with which two articles (such as an animal leash and a post, or two pieces of luggage) can be securely connected to each other. Embodiments of the invention can be quickly installed, quickly removed, and reused repeatedly as desired.

(6) Referring now to FIG. 1, an exemplary embodiment of a separable self-binding strap device 100 is illustrated, in accordance with the present disclosure. The separable self-binding strap 100 may comprise a bi-stable spring band 110 that is substantially covered on one side 120 with a Velcro hook (or loop) material or other similar fastening material, and is also substantially covered on the opposite side 130 with a corresponding Velcro loop (or hook) material or other similar fastening material.

(7) The bi-stable spring band 110 may comprise a flexible bi-stable spring band that may assume two equilibrium positions. In a first equilibrium position, the bi-stable spring band 110 may be substantially flat with a slight curve about its lengthwise axis, as shown in FIG. 1. To reach a second equilibrium position, the bi-stable hand 110 may be slapped across a roughly circular object, such as a rod, bar, dowel, post, wrist, ankle, arm, leg, handle, or other similar attachment point at which point the bi-stable spring band 110 may spontaneously transition from the first equilibrium position to the second equilibrium position, and thereby curl around the roughly circular object to remain relatively secure in that position.

(8) The bi-stable spring band 110 may be made of stainless steel, plastic, vinyl, or other suitable material and may be optionally sealed within a fabric, silicone, plastic, or other suitable cover.

(9) As shown in FIG. 1, the separable self-binding strap 100 may comprise a bi-stable spring hand 110 that is substantially covered on one side with a Velcro hook material 120 or other similar fastening material, and is also substantially covered on the opposite side with a corresponding Velcro loop material 130 or other similar fastening material. In one embodiment, the Velcro or other fastening material may be configured as a sleeve that contains and holds the bi-stable spring band 110. In another embodiment, the Velcro or other fastening material may be attached directly to the bi-stable spring band 110 by any suitable means known in the art, including glue or other forms of RF, chemical, or adhesive bonding, and/or riveting or other forms of mechanical or physical bonding. When attached directly to the bi-stable spring band 110, the loop component of Velcro or other fastening material may be attached to one side of the bi-stable spring band 110 and the hook component of Velcro or other fastening material may be attached to the other side of the bi-stable spring band 110.

(10) When the Velcro or other fastening material is configured as a sleeve to contain and hold the bi-stable spring band 110, the sleeve may comprise two opposing Velcro components (that is, a hook component and a loop component) that are placed back to back. In other words, the non-hook side of the hook Velcro component may be placed against the non-loop side of the loop Velcro component. The two components are then bonded together along three edges (typically two sides and one end), leaving one end open for insertion of the bi-stable spring band 110. After the bi-stable spring band 110 is inserted into the open end of the sleeve, the open end can be bonded, thereby enclosing the bi-stable spring band 110 within the sleeve and completing assembly the separable self-binding strap 100. Optionally, the bi-stable spring band 110 may be bonded to the inner surfaces of the sleeve by any suitable means known in the art. The process for bonding the edges of the sleeve together can involved the use of heat, stitching, glue, riveting, RE heat-sealing, or any other means known in the art.

(11) Either end of the separable self-binding strap 100 may be configured with any one or combination of the following affixing mechanisms: a hook, a clamp, an eye, an eyelet 140, a nail or any other affixing means suitable to secure the separable self-binding strap 100 to a fixed foundation such as a piece of wood, beam, pipe, wire, or other attachment point commonly found in homes, apartments, construction sites, vehicles, and spacecraft, for example.

(12) FIG. 2 illustrates an exemplary embodiment of a separable self-binding strap device in operation, in accordance with the present disclosure. As shown in FIG. 2, an embodiment of a separable self-binding strap 100 has been slapped across two roughly cylindrical objects that are held close to each other. In FIG. 2, these roughly cylindrical objects are shown as a rod or dowel 210 and a paint-can handle 220. Other examples of roughly cylindrical objects may include, for example, a ladder run, a post, a wrist, an ankle, an arm, a leg, a handle, or other similar structure. When a flat and straight separable self-binding strap 100 is slapped across the dowel 210 and the paint-can handle 220, the bi-stable spring band 110 may spontaneously transition from the first equilibrium position to the second equilibrium position and thereby quickly curl or coil around both the dowel 210 and the paint-can handle 220 to hold them relatively securely together, to enable the paint can 225 or other weighted article to be hung from the dowel 210. During the curling action of the bi-stable spring band 110, the opposing surfaces of the cooperating Velcro components (120 and 130) will come in contact with each other, which will cause their cooperating hook and loop Velcro components to join together, compressing hook against loop, to create a strong bond capable of resisting a force of at least 50 pounds.

(13) The separable self-binding strap 100 is separable because the interlocking Velcro components can be separated from each other, so the separable self-binding strap 100 can be returned to the first equilibrium position and reused in a later application. Normally, separation of the Velcro components (120 and 130) will require a force of a considerable magnitude when a large number of hooks are engaged with corresponding loops, but separation may be quite readily affected by progressively uncurling the separable self-binding strap 100, thereby peeling the cooperating hook 120 and loop 130 Velcro components apart. Unwrapping the separable self-binding strap 100 by an exterior end of the elongated bi-stable spring band 110 can increase the tension across the bi-stable spring band 110 until the coil is fully unwrapped and the curvature tension is applied as the bi-stable spring band 110 is elongated.

(14) Thus, continuing to refer to FIG. 2, embodiments of a separable self-binding strap 100 can he employed to quickly hang a weighted article (for example, paint can 225) from a hook, loop, rod, bar, flange, or other similar attachment point (for example, dowel 210), or to securely connect at least two articles together, by action of the curling and wrapping feature of the bi-stable spring band 110 together with the interlocking principles of the Velcro or other similar fastening material disposed along the full length of the bi-stable spring hand 110. For example, embodiments of a separable self-binding strap 100 can be employed: (1) to secure a paint can to a ladder rung, (2) to securely strap an electric saw by the handle to a construction beam, (3) to bind copper tubing to a secured pipe for easy access, (4) to strap a farm animal with a leash to a post, (5) to permanently or temporarily secure coiled wire for easy spooling, (6) to secure temporary fencing across a median to prevent breaching, or (7) to secure various pieces of luggage together.

(15) In one embodiment, the separable self-binding strap 100 may range from approximately 0.5 to 2 inches in width, and may range from approximately 3 to 12 inches in length. Other widths and lengths are possible and within the scope of the invention, based on the intended use and anticipated amount of resistance required.

(16) FIG. 2 illustrates the use of one separable self-binding strap 100, but more than one embodiments of the invention can be used together, serially, or in parallel.

(17) Although the present disclosure provides certain embodiments and applications, other embodiments apparent to those of ordinary skill in the art, including embodiments that do not provide all of the features and advantages set forth herein, are also within the scope of this disclosure.

(18) The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. It will be appreciated that modifications, variations and additional embodiments are covered b the above teachings and within the purview of the appended claims without departing from the spirit and intended scope of the invention. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
